LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 653,969, dated July 17,1900.

Application tiled March 30, 1900.

To all whom it may concern:

Be it known that I, JAMES C. SERGEsoN, a citizen of the United States,residing in the city and county of Philadelphia, in the State ofPennsylvania, have invented a new and useful Improvement inLoom-Shuttles, which improvement is fully set forth in the specificationand accompanying drawings.

My invention consists of a shuttle which is provided withV means whichby the motion lof the spindle may be automatically engaged with a bobbinand automatically disengaged therefrom.

Figures l and 2 represent top or plan views of a shuttle embodyingl myinvention. Fig. 3 represents a side elevation thereof, a portion of thebody of the shuttle being cutaway. Figi 4 represents alongitudinalsection thereof. Fig. 5 represents a partial end view and partialtransverse section on line a: Fig. 4.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates a shuttle in general respects ofusual construction.

B designates the spindle,0 the head thereof, and D the axis of saidhead.

E designates the jaws, which are mounted on said head by the pivot F,whereby they are permitted to open and close in the direction of thewidth of the shuttle. The heel or rear ends of the jaws are curved ortapering and have depending ears G, which freely enter the recesses H inthe head C, so as to be guided therein as the jaws open and close.Interposed between said ears is the spring J,

whose tendency is to close the jaws and hold 4 them closed, said springoccupying the chaml ber K in the head C and bearing against the ears.

L designates shoes which are seated on the recess M in the head C,V saidrecess being par-V allel with the recesses II and permitting the shoesto rock on said head. Bearing against the back of the connecting-piece Nof the shoes is the coiled spring P, which rests freely in the nose orend portion of the body of the shuttle and encircles the stem L of theshoes L, thus retaining the shoes in position on the head C. The shoesare adjacent to the heel ends of the jaws E and have their inner sides Qpreferably inclined or converging, said heel Serial No. 10,744. (Nomodel.)

-dle is lowered and returned, the heel ends of the jaws then clearingthe shoes L and the spring J becoming operative and separating the heelends of the jaws, whereby the latter close on the bobbin and tightlyclamp and hold the same. The spring P, which in a measure works with theshoes L, now presses upwardly against the wall of the recess N and soholds the spindle in closed position. In

(order to release the bobbin, the spindle is raised, when the heel endsof the jaws enter between the shoes L and are brought together, wherebyowing to said heel ends or heels, which are curved or tapering, the jawsseparate and are removed from the bobbin, the latter thenbeng free to beslipped off of the spindle.

The jaws are angular or deiiected and have curved faces, so as to nicelyenter the groove of the bobbin and properly engage with the wallthereof.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A shuttle having pivotal jaws mounted on the head of the spindlethereof and shoes on the body of the shuttle between which the heel endsof^said jaws are adapted to ride, and a spring bearing outwardly againstsaid heel ends,whereby when the spindle is raised said jawsautomatically leave the bobbin on said spindle and when said spindle islowered, said jaws automatically close on said bobbin.

2. A shuttle having pivotal jaws on the i head of the spindle thereofand shoes between whose inner faces the heel ends of the jaws areadapted to ride, whereby, when the spindle is raised, the jaws areautomatically disengaged from the bobbn.

3. Ajshuttle having laterally-movable jaws pivoted on the head of thespindle thereof and adapted to embrace a bobbin, and a spring bearinglaterally against the heel ends of said jaws, whereby when the spindleis lowered, said jaws automatically engage said bobbin and retain theirhold thereon.

4. A shuttle having pivotal jaws on the head of the spindle thereof andshoes on whose sides the head ends of the jaws are adapted to ride,whereby when the spindle is raised, the jaws are automaticallydisengaged from lLhe'bobbin, and springs bearing laterally against saidheel ends, whereby when the spindle is lowered, said jaws automaticallyclose upon said bobbin.

5. In a shuttle, a spindle, a head carrying the saine, laterally-movablejaws pivoted on said head, a spring bearing laterally against the heelends of said jaws, shoes mounted on said head and adapted to engage saidheel ends when the spindle is raised, and a spring on the shuttleengaging said shoes and serving to hold the shoes on the head, andretain the spindle either in open or closed position.

6. In a shuttle, a spindle, a head carrying the same, jaws mounted onsaid head adapted `t0 engage a bobbin on said spindle, and a springbearing against the heel ends of said jaws to close the latter, saidheel ends having depending ears and said head having recesses whichfreely receive said ears.
